Crystal structure of Ti₄Ni₂C

Ti₄Ni₂C crystallizes isotypically with Ti₄Ni₂O, Nb₄Ni₂C and Ta₄Ni₂C and can be considered as a partially filled Ti₂Ni structure with the C atom occupying an octa­hedral void.

Di­chlorido­(4,7-dimeth­oxy-1,10-phenanthroline-κ²N,N′)zinc(II)

In the crystal structure of the title compound, the central zinc(II) metal atom is surrounded by two N atoms of a bidentate 4,7-meth­oxy-1,10-phenanthroline ligand and two chlorido ligands in a distorted tetra­hedral coordination environment.

trans-Di­chlorido­bis­[(S)-(−)-1-(4-methyl­phen­yl)ethyl­amine-κN]palladium(II)

The mol­ecular Pd^II title complex exhibits a square-planar coordination about the central metal atom, provided by two trans-arranged chlorido ligands and two nitro­gen atoms from the two neutral organic ligands.

Synthesis and structure of trans-bis­(4-amino-3-nitro­benzoato-κO)bis­(4-amino-3-nitro­benzoic acid-κO)di­aqua­manganese(II) dihydrate

The reaction of 4-amino 3-nitro­benzoic acid and manganese dichloride tetra­hydrate in an ethanol–water mixture yielded the title complex[Mn(C₇H₅N₂O₄)₂(C₇H₆N₂O₄)₂(H₂O)₂]·2H₂O. In the crystal, mol­ecules are linked by N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds.

Bis[1,3-bis­(2,4,6-tri­methyl­phen­yl)imidazolium] bis­(μ-cis-1,2-di­phenyl­ethene-1,2-di­thiol­ato-κ²S,S′:κS)bis­[(cis-1,2-di­phenyl­ethene-1,2-di­thiol­ato-κ²S,S′)iron(III)] di­methyl­formamide disolvate

The solid-state structural analysis of a reduced iron bis­(di­thiol­ene) dimer reveals that the mol­ecule crystallizes with the center of the Fe₂S₂ ring system on a crystallographic center of inversion. The structure shows non-classical hydrogen-bonding inter­actions between imidazolium H atoms and the oxygen atoms of N,N-dimethyl formamide that co-crystallized together with the title compound.

(4-Butyl-1-ethyl-1,2,4-triazol-5-yl­idene)[(1,2,5,6-η)-cyclo­octa-1,5-diene](tri­phenyl­phosphane)rhodium(I) tetra­fluorido­borate

In the title triazole-based N-heterocyclic carbene rhodium(I) cationic complex with a tetra­fluorido­borate counter-anion, the Rh center has a distorted square-planar coordination geometry with expected bond distances.

Bis(2-hy­droxy-2,3-di­hydro-1H-inden-1-aminium) tetra­chlorido­palladate(II) hemihydrate

In the title salt hydrate, (C₉H₁₂NO)₂[PdCl₄]·0.5H₂O, the Pd^II atom is coordinated by four chloride anions and the charge balance is provided by two ammonium cations formed from (1R,2S)-(+)-1-amino­indan-2-ol.

Bis[2,6-bis­(benzimidazol-2-yl)pyridine-κ³N,N′,N′′]nickel(II) bis­(tri­fluoro­methane­sulfonate) di­ethyl ether monosolvate

In the crystal structure of the title compound, the nickel(II) metal center is surrounded by two tridentate 2,6-bis­(2-benzimidazol­yl)pyridine ligands in a distorted octa­hedral geometry. Hydrogen bonding is present between counter-ion and ligand.

rac-Hy­droxy­isovaleric acid

The title compound is the constitutional isomer of α-hy­droxy­butanoic acid. In the crystal, hydrogen bonds involving the alcoholic hydroxyl group give rise to centrosymmetric dimers that are extended to sheets perpendicular to the crystallographic c axis.

5,6-Di­methyl­benzo[d][1,3]oxatellurole

The title compound represents the first reported example of a [1,3]oxatellurole, prepared in three steps from 3,4-di­methyl­phenol. Both independent mol­ecules are folded along their Te⋯O axes, with an average angle φ = 25.1° between the Te–C–O planes and the remaining non-hydrogen atoms. A Hirshfeld plot indicates a weak inter­molecular inter­action between the two tellurium atoms in the asymmetric unit.

N-Methyl-2-{3-methyl-2-[(2Z)-pent-2-en-1-yl]cyclo­pent-2-en-1-yl­idene}hydrazinecarbo­thio­amide

The synthesis, crystal structure and Hirshfeld analysis of cis-jasmone 4-methyl­thio­semicarbazone is reported. Two crystallographically independent mol­ecules are observed in the asymmetric unit, one of them being disordered over the carbon chain. In the crystal, the mol­ecules are linked by N—H⋯S and C—H⋯S inter­actions into independent centrosymmetric dimers.

2-Amino­benzoxazole–oxalic acid (2/1)

In the title compound, proton transfer from oxalic acid to the N atom of the heterocycle has occurred to form a 2:1 molecular salt. In the extended structure, N—H⋯O hydrogen bonds link the components into [100] chains, which feature R²₂(8) and R⁴₄(14) loops.
